People with borderline personality disorder( BPD ) have often experienced chronic invalidation / abuse as well as having a genetic predisposition. Because of this, the process of forming an identity has been disrupted.
A pw BPD is unable to make sense of his /her environment and internal experience to it because no-one has asked or spoken about her experience or how she feels from early childhood, or provided reassurance. Her external environment is frightening and causes chronic hypervigilance associated with emotional, cognitive and behavioural dysregulation and neuroendocrine dysfunction.
There is no framework for forming a strong sense of identity and difficulty thinking about the mental states of oneself and others regarding dreams, thoughts, emotions, and goals (known as mentalising). The pw BPD may experience identity diffusion (described as not knowing where they end and another person begins) and poor boundaries.
This prevents the integration of essential learning, about what is normal, into a child's personality which can lead to confusion, poor coping methods, difficulty forming healthy relationships, mistrust, chronic anxiety and depression.
The brain structure and function will be altered depending on the length of trauma exposure, timing and effectiveness of therapy.
‘HPA-axis dysfunction in BPD largely mirrors findings demonstrated in post-traumatic stress disorder and may represent a valuable neuroendocrine target for diagnostic or treatment response biomarkers, or for which novel treatments can be investigated.’
